Abstract (en)
To provide machining devices with which milling can be continued even after a machining tool is judged as being unusable during milling. A machining device including: a milling mechanism for carrying a machining tool and being for milling a workpiece; a detection mechanism that detects a length of the machining tool; a storage mechanism that holds a plurality of machining tools; a workpiece changing mechanism being capable of changing the workpieces to be milled by the milling mechanism; a memory unit that memorizes a group of commands, the group of commands including a machining command for forming the modeled object to the workpiece, a tool usability judging command for judging usability of the machining tool, and a workpiece change command for changing the workpieces; and a control unit that skips over, when it judges, as a result of the execution of the tool usability judging command, that the machining tool in use cannot be used anymore because the length of the machining tool in use is equal to or smaller than a predetermined value, one or more commands which have been scheduled to be executed before the workpiece change command to be executed for the first time after the tool usability judging command.
